Great work Dr. Astro! Much appreciated for the info. Its a shame the thread is full of people I'm not even sure took the time to watch it before posting such dumb shit. Its all laid out in the video people, just watch it before jumping to ridiculous conclusions you pulled from your ass. Follow the facts! Great job though Astro, really well put together my friend and taught me something about old comets I never knew! Cheers

A very wise man with diahrea once said..."sometimes shit just happens"

Because I ran it through ORSA for over the next 10,000 years (in fact I ran it out to about a million years in one simulation; it reached a light year distance in that time) and its eccentricity remained over 1 during the next 10,000 years. In fact the average eccentricity for that period was 1.000002. JPL's Horizons concurs with my ORSA analysis but doesn't integrate the orbit over nearly as long a time period as I did.

Interesting that before the telescope become common in the early 1600's, between the period of 87 BC and 1600, there were 34 great comets, 20 of those were appearances of Comet Hally.

Since 1600 there has been 27 great comets, only 2 of those were of Comet Hally.

So since 87 BC, of 61 known great comets, 22 of those were Hally, and 39 other great comets as yet unrelated.

I wonder if anybody has checked those other 39 great comets in history to make sure they were not related like the 22 Hally appearances? Probably, but wouldn't surprise me if no one had. (Hint, hint, Astro(

Curious that the only recurring great comet in history is Comet Hally.

Though the record indicates that we might be better at spotting great comets since the age of the telescope, some of these great comet appearances were brief, and alot of great comets have been lost to history.

Maybe there is another recurring great comet out there. Maybe. Maybe not. Probably...

it is not named after the people who 'found' it but rather the scope that viewed it- is this due to it haveing been witnesed and named many times through the years?ISON has no name, but the scope that viewed it is called ISON.strange no?

Hyperbolic means it has an orbit eccentric level 1, and its end orbit is UNKNOWN (it is said it MAY return, not it will NOT)

ISON's origin is not know, but it might be from the ort cloud

this means ISON may not have visited this solar system before, but no records indicate either it has or it has not

Thanks, Dr. Astro, for a good video explanation of the various comets. There is so much fanciful speculation going on that's it's always a pleasure to watch empirical evidence presented. And, I like your voice as well.

the question that should be asked but noone seems to ask is just like the story of 9/11 building 7 is the giveaway for the biggest hoax on Earth is why did Nasa stop making public things about comet Ison passing Mars.That is the dead giveaway that something big is amiss with Ison and no doubt they still monitoring this rock second after second but do not publish their findins.Very very fishy and yet all seem to accept that it is normal behaviour for a once-in-a-civillization comet passing that Nasa shuts observations down due to government shutdown.They had interest in comet Haley I tell you, this Nasa and comet Ison stink into heaven.Maybe this whole government shutdown was created for Nasa to give them a reason to not waken up the sheople of something incoming?

Because I ran it through ORSA for over the next 10,000 years (in fact I ran it out to about a million years in one simulation; it reached a light year distance in that time) and its eccentricity remained over 1 during the next 10,000 years.

Another interesting question raised.

The simulation of ISON was ran out about a million years, reaching a light year distance in that time. And indications that if you ran the simulation further, the distance would be even further out.

Considering that the closest star to Earth is a little over 4 light years away, and there are 8 stars within 10 light years, if ISON were interstellar, it would only make sense that it came from one of our closest neighbors.

I wonder if anyone has checked whether ISON is coming from the direction of one of our nearest stellar neighbors, or some particular point of interest?

Interstellar material is real and exists here on Earth. In the study of meteorites, there has been examples of heavy elements in certain meteorites, that do not and could not originate in our solar system. These meteorites are believed to be of interstellar origin, found right here on terra firma.

Totally believe in that whole panspermia theory of Wickramasinghe and Hoyle, of interstellar comets distributing life creating elements throughout the universe.

From Astro's own figures, ISON might not just be a good show from our region of space, but may be seeding interstellar elements into our solar system, until all civilization is destroyed!

umm.. I don't get it, you create a thread asking if there's a 333 year correlation & a video which may or may not support your question,

Actually the video definitively rules it out.

Quoting: Dr. Astro

The person who created the youtube video with the very kind and gentle countenance, stated 3 times in the video between 1:10 and 1:45 that ISON and the Comet of 1680 are "probably not related" and "may not be related".

The video, which is MINE, definitively rules out the 333 year orbit. I SPECIFICALLY SAID it is a hyperbolic comet, it does not have a 333 year orbit. The comet of 1680 is probably completely unrelated, but related does not mean "the same comet."

Yet you come on GLP and claim that "there is no way in hell they are related"

Quoting: troll

Quoting what I actually said.

there is no way in hell for ISON to be on a 333 year orbit, or "comet Negra" to be related to it.

the same can be applyed to Astros videohowever astro claims to know what nobody knows

he compares a comet with a hyperbolic (eccentric orbit) to previous comets orbits, and claims it CANT be related, due to the orbit being to erratic and slightly out of sync, so unrelatable

Quoting: Shadow Beam

No, you clearly didn't understand my video. The comets of 1347 and 1014 can't be ISON or related to ISON because their orbits are completely different from ISON's. Sungrazer comet families have related orbits, but those orbits resemble each other because they are related.

you claim to caculate a predicted orbit model with a method which by definition means un-certain

Quoting: shadow

Word salad. Hyperbolic does not mean we can't analyze it or compare it to other comets.
